Grand Cayman has a public minibus service, but it's elusive; renting a car is the best way to explore the island. On the sister islands of Little Cayman and Cayman Brac, it's virtually the only form of transport. You can rent from agencies at the airport or have a car delivered to your hotel. The required driving permit is available from your rental agency for US$7.50; you must be at least 21 and carry a valid driver's license from home. Motorcycles and scooters are also available on all three islands. Traffic moves slowly, with refreshing courtesy and on the left.
You can take a taxi anywhere on Grand Cayman, though availability drops off the farther you get from George Town. Taxis are not available on Little Cayman or Cayman Brac. You can take a ferry between North Sound and Rum Point on Grand Cayman, which takes about 40 minutes each way. The Caymans are flat and small enough that getting about by bicycle is feasible, so long as you're not ferrying scuba gear. Bicycles are available for hire.
Short of chartering a private boat, the only way to get from Grand Cayman to the sister islands is by air. Island Air flies small prop planes to Cayman Brac and Little Cayman in about half an hour. Cayman Airways flies 737s to Cayman Brac but doesn't offer a service to Little Cayman. Island Air's puddle jump between Cayman Brac and Little Cayman takes about seven minutes - you can see the runway you're approaching as soon as you take off!
Grand Cayman's Owen Roberts Airport is less than 2 miles (3km) south of George Town, and taxis are plentiful for the trip into town. Gerrard-Smith Airport is located at the western end of Cayman Brac. On Little Cayman, Edward Bodden Airfield is located just west of South Town, on the southwestern coast. Neither of the smaller islands have an airport taxi service, but hotels will pick travelers up. There's no ferry service from Grand Cayman to either of the sister islands, but private boat operators will shuttle you between Cayman Brac and Little Cayman for about US$20 (20 minutes).
